Former Essendon coach Kevin Sheedy chats to Fox Sports News about the Bombers doping scandal, saying anyone found guilty should be banned from the AFL.

FREMANTLE CEO Steve Rosich has admitted the club has injected players with vitamins to aid their recovery but said the Dockers have nothing to fear from investigations stemming from the bombshell Australian Crime Commission report.

Rosich was also adamant Fremantle players did not take anything illegal provided by former sponsor Nutrition Systems, the supplements company whose parent company was fined more than $3m for importing and supplying unregistered substances.

Nutrition Systems sponsored the Dockers in 2008 and 2009.

"It was essentially a marketing contract. It was a non-exclusive supply arrangement," Rosich said.

"We vetted the products that we utilised and that process as we normally would, so we're very comfortable.

"I'm really comfortable with our people, our structure, our processes, so no, we don't have a major concern at the Fremantle Dockers.

Rosich did not believe the year-long ACC probe had looked at Fremantle.

"The short answer is we don't know definitively, but every indication is from what we know that no, we weren't part of that,'' he said.

"Our club has a food-first focus, and the supplements are obviously part of that process, but they are only a minor part of it.''

Rosich said players sometimes received injections to aid recovery.

"In some instances, if a player's feeling that way that they need a quick infiltration of vitamins, but no only natural substances in that context,'' he said when asked if players were injected with supplements.
